Use of subjective information in scientific psychology: III. The internal image during visual perception: an introspectionist analysis.

Perceptual and Motor Skills June 1, 1990 G Gillespie

Drawing on personal observation, the author describes features of hypnopompic visual imagery—images seen upon waking—that illuminate how internal visual images are experienced. This understanding explains how a two-dimensional internal perceptual image can be experienced as a three-dimensional external environment surrounding the observer. The author suggests how this three-dimensionalized perceptual image is constructed, how it creates the effect of directional looking within a wide field of view, and how certain features of visual perception are best accounted for by the mediation of perception through an internal image.

Lights and lattices and where they are seen.

Perceptual and Motor Skills April 1, 1989 G Gillespie

The author describes personal observations of persistent bright lights that appear during lucid dreams and upon waking (hypnopompic states). These lights—such as areas of light, disks, or sun-like concentrations—remain fixed in the visual field regardless of dreamed body movements and recur in the same locations across different dreams. Unlike ordinary dream images, they are not representational. The author notes that hypnopompic geometrical patterns, though appearing dome-like, are actually experienced as two-dimensional and flat. This flatness, the author argues, applies to all internal images, which the mind then translates to external positions around the eyes.
